摘要
In this paper, we present a method to reduce the sidelobe levels of a given parabolic reflector antenna by coating it with a 2-layer absorber. The absorber is designed by using Genetic Algorithm and an ultra-wideband performance (4.6-18 GHz) is obtained. The simulation results show that the sidelobe level can be reduced by coating the edge of the parabola with 2-layer absorber without compromising the gain.
